Who knows about turn signal wiring?

I used switchback LEDs in my reverse lights. White when reverse, amber for signal. The only thing I give up is turn and reverse at the same time, turn would override reverse.
You can get white/red switchbacks of you would prefer to stay with red, but since the reverse is within the same housing/cluster as my turn/brake/tail, and I wasn’t cancelling brake, I wanted some differentiation. Besides, amber is a safer worldwide standard.
I did have to add a wire to make them two different circuits
Oh, and I did need to change the reverse socket to a 2-pin 1157 style from the 1 pin reverse only.

As a side note, I also used switchback lights in my front turn housing. I can turn on the front park lights as DRL without using park and running all the markers, tail, & dash lights. When I apply turn, the switchback turns off the white & flashes amber, when it detects no flash signal for more than 1 second, it will go back to white (again-only IF I have white turned on)
